System information
Changing the playback rate of or undersample a video event
1. Right-click the event and choose Properties from the shortcut menu.
2. On the Video Event tab, adjust the Playback rate and Undersample rate controls.
Setting Description
Playback rate Enter a value in the box to set the rate of playback. For example, a
setting of 1 will play at normal speed, while 0.5 will play at half
speed.
Each video event in your project has a specific duration that is not
changed by adjusting the playback rate. If you decrease the speed of
a ten-second video event by 50%, only five seconds of video will be
shown. On the other hand, if the speed is increased 200%, the ten
seconds of video will play in only five seconds. The remaining five
seconds of the event will be filled either with a freeze of the last
frame or with ten additional seconds of video content from the
media file (if the source media is longer than the event).
Undersample rate Enter a value in the box to simulate a lower frame rate. For example,
if you enter 0.5 in the box, the event will play at half its original
frame rate, and each frame will be held twice as long as in the
original media file, creating a strobe effect.
3. Click the OK button.
